SUPPORT.

Specification of Letters Patent.

Application filed July 15, 1919. Serial No. 310,898.

To all whom it may concern.

Be it known that I, THERON H. HAWKES, Jr., a citizen of the UnitedStates, residing at Duluth, in the county of St. Louis and State ofMinnesota; have invented new and useful Improvements in Supports, ofwhich the following is a specification.

This invention relates to means for supporting covers of cabinets inopen position, and the principal object of the invention is to providemeans whereby the support will be released, so that the cover may beclosed by a movement of the cover.

Another object of the invention is to provide means-whereby the openingmovement of the cover will set the parts to hold the cover in openposition and a further movement of the cover will move the parts topermit the cover to be closed.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a view of a phonographic cabinet supplied with my invention;

Fig. 2 is an enlarged detailed view showing the parts in position forsupporting the cover in open position;

Fig. 3 is a like view with the parts in an other position;

Fig. l is a sectional view of the supporting plate and some of theattached parts;

Fig. 5 is a view of a slightly diflerent arrangement of the parts; a

Fig. 6 is a view of the device applied to a cabinet which has its doorin one side thereof.

In these views 1 indicates the cabinet and 2 the cover thereof which ishinged to the top edge of the cabinet in the ordinary manner. Asupporting arm 3 is pivoted at its upper end to the cover 2 by the pin4. A plate 5 is secured to the inner side of the upper portion of thecabinet by means of screws or the like and this plate is provlded with aflange 6 at its upper edge in which is a slot 7 through which the arm 3passes. This arm is provided with a stop projection 8 to limit theupward movement of the cover as this stop will strike the flange andthus prevent further movement of the arm. The arm is provided with arecess 9 adjacent its free end which is provided with a curved bottomwall with the ends cut so as to provide the catches 10 and 11. The platecarries a guiding arm 12 which extends over the arm 3 for guiding thesame in its movement. A disk 13 is pivoted to the plate by means of thescrew 14- and said disk has its periphery provided with a number ofgroups of notches, as shown. Each group comprises a pair of notches ofsubstantially V-shape, as shown at 15 and 15' and a third notch 16 whichextends in a different direction to the other two notches. This notch 16is adapted to be engaged by the upper catch 11 to support the cover inopen position while the other two notches are adapted to be engaged bythe catch 10 at the lower end of the arm for rotating the disk. Thesenotches 15 and 15 are also adapted to be engaged bya pawl 17 pivoted tothe plate and yieldingly held against the edge of the disk by a spring18 located on a guiding arm 19 connected with the plate. This pawl willprevent the disk from being moved in a clockwise direction but willpermit it to move in the reverse direction. A spring 20 carried by thecover 2 engages the supporting arm 3 to cause the catches 10- and 11 toengage with the notches of the wheel or disk.

It will thus be seen that when the cover is raised until the stop 8strikes the flange on the supporting plate the catch 10 will engage thenotch 15 and cause the disk to turn until the notch 15 will occupy theposition of the notch 15 and the pawl will engage with the next notch ofthe second group of notches. The first group of notches shown at the bottom of the wheel will advance into a position where the middle notch maybe engaged by the catchlO on the next upward movement of the same. Thecover may then be closed as the notch 16 will be moved to a positionwhere it cannot be engaged by the catch 11 so that said catch willsimply slide over the periphery of the disk and the parts may occupytheir lowered position. The disk is prevented from being rotated by thepawl. When the cover is raised again, the catch 10 will engage themiddle notch of the next group so as to place the stop notch 16 of thisgroup in a position to receive the catch 11 when the cover is partlylowered again.

Patented Mar. 2, 1920.

It will, of course, be understood that the notches are arranged so thatthis operation may be carried out indefinitely. By raising the cover asfar as it will go and then partly lowering the same, the catch 11 willengage the stop notch and the cover will be held in open position. henthe cover is to be closed it is first raised again to its full openposition so as to move the stop notch out of engaging position and thusthe cover may be lowered.

Tn the modification shown in Fig.5, the arm 3 is placed on the oppositeside of the disk and a spring 3 is provided "for holding the arm againstthe disk. In other respects this form of invention is similar to thatjust described.

Fig. 6 shows the invention applied to a cabinet 1 which has its openinglocated in one side thereof so that the door or cover 2 swings outwardlyand upwardly. The various parts of the invention in this case arearranged substantially as first described.

While I have shown and described the device as applied to cabinetphonographs, it will, of course, be understood that it may be applied tocabinets used for other purposes.

What I claim is 1. In combination with a cabinet and its cover, asupporting arm for the cover having one end pivoted thereto, catchesadjacent the other end of said arm, a disk carried by the cabinet, stopmeans on the disk for en gaging one of the catches "for holding the armin position with the cover open and means on the disk operated by theother catch for moving said stop means into and out of operativeposition.

2. In combination with a cabinet and its cover, an arm pivoted to thecover and having a pairof catches thereon oppositely arranged, a notcheddisk on the cabinet having the notches therein arranged in groups, eacngroup consisting of a pair of notches spaced apart and extending in thesame direction 3. In combination with a cabinet and its cover, an armhaving one end pivoted to the cover, a plate carried by the cabinet andhaving a slotted flange thereon through which the arm passes, a stop onthe arm for engaging the flange to limit the upward movement 1 I of thecover, upper and lower catches on the said arm, a disk carried by theplate, stop means on the disk for engaging the upper catch to hold thecover in partly raised position and other means on the disk adapted tobe engagedby the lower catch when the cover is raised to rotate the diskto move the stop means into and out of operative position.

4. In combination with a cabinet and its cover, an arm having one endconnected wlth the cover, a plate carried by the cabinet, a flange onthe upper edge of the plate having a slot therein through which the armpasses. upper and lower catches on one edge of said arm, a stop on theother edge for limiting the upward movement of the cover by engagingwith the flange, a guide arm on the plate for said supporting arm, adisk pivoted to the plate and having groups of notches in its periphery,some of said notches being arranged to be engaged by the lower catchwhen the arm is raised to rotate the disk in one direction and one ofthe notches of each group being adapted to be engaged by the upper catchfor holding the arm against downward movement and a pawl engaging someof said notches for preventing rotation of the disk in the oppositedirection.

In testimony whereof I aflix my signature.

THERON H. HAWKES, JR.
